answer:Sounds like the battery. It may have had a small bit of juice left for the doors to open. You attached the cables and power started flowing. It may have just made that clicking sound because you didn’t let the battery get rejuiced up enough before attempting to start. If you happen to get it started, while running, disconnect the negative terminal from the battery. If the engine dies, you have a bad alternator. If it stays on, your battery was dead and may need replacing. Of course this is a lot of guessing based on experience and what you offered as a description to a problem. If I were you, I’d try the cables again, letting the stay connected for like five minutes before attempting to start the car. Good luck. :-)
